Backend Developer (Telephony, Faxing)

Description

Alohi SA brings together a team of highly competent engineers that focus on merging state-of-the-art technologies with compelling user experience in order to simplify and enhance life for companies and people around the world. The company provides Sign.Plus (a legally binding electronic signature), Fax.Plus (online faxing), Dial.Plus (AI-voice agent), and Scan.Plus (AI-powered mobile scanner) services to over 4,000,000 customers worldwide.

At Alohi, we began our journey with an initial seed investment from Fongit “Fondation Genevoise pour l’Innovation Technologique” which is backed by the state of Geneva. But instead of relying on external funding to fuel our growth, we’ve chosen to bootstrap our way to success. This approach has allowed us to prioritize our customers and build products that truly meet their needs, without being beholden to outside investors. By remaining financially independent, we’ve been able to maintain our autonomy and agility, which have been key factors in our ability to innovate and stay ahead of the curve.
